Project information
»The problem
Worldwide, the potato crop is the biggest single user of pesticides.
Insect pests are the major constraint to increasing potato
yields, especially in tropical and subtropical regions. Heavy
use of pesticides has resulted in several problems. Some pests
have developed resistance to pesticides, secondary pests are
emerging, beneficial insects are being destroyed, and the
environment suffers.
»The approach
The project is developing potatoes that resist insects and
therefore need less pesticide. It is exploring two types of
insect resistance derived from wild relatives of the cultivated
potato. Although these types of resistance were known to provide
resistance only to the potato foliage, potato clones with
resistance to tuber pests have been produced. The project
has made progress since its inception in 1995, but potato
breeding takes a long time and finished varieties are not
yet available. The project is continuing to document the potential
reductions in pesticide use associated with the resistant
clones; to encourage farmers to use these resistant potatoes
in the context of integrated pest management; and to advance
socioeconomic studies to provide baseline data for future
evaluation of impact.
»The goal
To enhance food security and minimize the health and environmental
impact of insecticides by developing resistant potato varieties.
